have not configured any channels to be part of the scan list. Otherwise, all
channels on the module are break-before-make.
34903A 20-Channel Actuator / General-Purpose Switch
– 300 V, 1 A actuation and switching
– SPDT (Form C) latching relays
– Breadboard area for custom circuits
– For detailed information and a module diagram, see page 155.
Use this module for those applications that require high-integrity contacts or
quality connections of non-multiplexed signals. This module can switch 300 V, 1 A
(50 W maximum switch power) to your device under test or to actuate external
devices. Screw terminals on the module provide access to the Normally-Open,
Normally-Closed, and Common contacts for each of the 20 switches. A
breadboard area is provided near the screw terminals to implement custom
circuitry, such as simple filters, snubbers, or voltage dividers.
34904A 4x8 Two-Wire Matrix Switch
– 32 two-wire crosspoints
– Any combination of inputs and outputs can be connected at a time
– 300 V, 1 A switching
– For detailed information and a module diagram, see page 156.
Use this module to connect multiple instruments to multiple points on your device
under test at the same time. You can connect rows and columns between multiple
modules to build larger matrices such as 8x8 and 4x16, with up to 96 crosspoints
in a single mainframe.
34905/6A Dual 4-Channel RF Multiplexers
– 34905A (50Ω) / 34906A (75Ω)
– 2 GHz bandwidth with on-board SMB connections
– 1 GHz bandwidth with SMB-to-BNC adapter cables provided
– For detailed information and a module diagram, see page 158.
